Overview
The Carlo Gavazzi BD35 is the base display unit of the UDM35 modular indicator and controller series. The BD35 features TRMS AC current and voltage measurements and serves as the foundation for scalable measurement and control systems. The UDM series features a rugged 1/8 DIN housing, rated IP67/NEMA4x. This face-only unit requires pairing with input modules (such as BQTRX for thermocouple or resistance temperature input) and power supply modules (such as BPH for AC/DC operation).
Key Features
- Easy and quick parameter programming and parameter cloning via UdmSoft or PC HyperTerminal
- 3.5-digit LED indicator with IP67, NEMA4x front protection
- Min/max recording, data hold, display/input range scaling, and password protection
- Microprocessor-based design for reliable, repeatable measurements
- Supports current (200 μA to 5 A), voltage (200 mV to 500 V), temperature (Pt100, Ni100, TC J/K/S/T/E), resistance (20 Ω to 20 kΩ), and frequency (0.001 Hz to 50 kHz) measurements
Technical Specifications
Typical Applications
Digital panel meters perform critical monitoring and control of variables such as temperature, pressure, and vibration in automation and process control applications, and can provide analog and/or serial re-transmission of measured values for feedback or data-logging. The BD35 is well-suited for:
- Electrical distribution panel monitoring
- Process temperature and pressure measurement
- Frequency and speed monitoring in motor control
- Industrial automation control cabinets
Compatibility & Replacements
Compatible With
- BQTRX input module (thermocouple and RTD input)
- BPH power supply module (AC 90–260 V and DC 10–28 V operation)
- Optional BO relay output and analog output modules
- UdmSoft configuration software
- PC HyperTerminal for parameter programming
Replaces / Drop-In Replacement For
The BD35 base unit is the standard face component of the UDM35 series. Verify specific interchangeability with your system integrator, as the BD35 requires paired input and power modules for operation.
Works With
- Optional RS422/RS485 serial communication modules
- Min/max data recording functions
- Scalable multi-input measurement architecture
